About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX40-10
The AirTAC SAIJ100X40-10 is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. This fine-tuning capability is ideal for dialing in exact end positions at commissioning without adding external stops.
This SKU is configured with a SUS304 stainless steel rod (code B) for superior corrosion resistance and features PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, ready for CMSE reed or DMSE electronic switches if a magnet is added later. It supports the standard SAIJ mounting set, including Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3682 N | 3682 N |
| 0.7 MPa | 5154 N | — |
| Max (@1.0 MPa) | 751 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX40-10 Is Used
Precision End-Stop Tuning
Dial in the exact 30-40mm travel window during machine commissioning to perfect the clamping distance without machining custom spacers.
Product Size Changeovers
Quickly adjust the rear stopper by up to 10mm to accommodate slight variations in incoming part sizes on a high-speed line.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX40-10 the Right Cylinder?
Choose this 100mm bore when you need substantial thrust—stepping down to an 80mm bore drops the 0.5MPa push force to 2513N. The adjustable stroke is perfect for applications requiring variable end-stops or frequent product changeovers, unlike a fixed-stroke SAI cylinder. Remember that the rear adjuster is a travel stop, not a lock; the SAIJ cannot hold a load without live air, so consider a SAIL or BSAI model if load-holding is required.
For replacing an ISO 15552 cylinder, match the 100mm bore, 40mm stroke, 10mm adjustment range, G3/8 port, and mounting style. Because the stroke is under 300mm, side-load stress on the 25mm rod is minimal, but an external guide remains recommended for heavy lateral loads.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAIJ100 Adjustable Cylinder SAIJ100BX40-10 FAQ
The rear adjuster acts as a mechanical stop that lets you shorten the 40mm nominal stroke by up to 10mm, creating a 30-40mm usable travel window. It only sets the end position and does not lock the load without continuous air pressure.
